Motorola phones where using Qualcomm modems. There is nothing really special about it. Even the Nexus had the same modems during that time period. Pixel phones didn't have widespread modem issues until they switched to Samsung modems starting with Pixel 6. Not sure what is there to tell about it other than Qualcomm makes good modem. Even the iPhones with Intel modems where inferior to Qualcomm modems and thank god they switched back to Qualcomm with iPhone 12.
